We consider a Mobile Ad-hoc NETworks (MANET) formed by n nodes that move independently at random over a finite square region of the plane. Nodes exchange data if they are at distance at most r within each other, where r > 0 is the node transmission radius. The flooding time is the number of time steps required to broadcast a message from a source node to every node of the network. Flooding time...

The Synchrotron Radiation Source (SRS) at Daresbury Laboratory has a 600MeV Booster, fed by an energy storage power supply configuration (White Circuit). The design consists of two power supplies : an AC source to supply the losses to the parallel resonant circuits and a DC supply to fully bias the AC sinewave. In a recent modernisation of the control electronics, different methods of achieving...

Power decoding, or “decoding using virtual interleaving” is a technique for decoding Reed–Solomon codes up to the Sudan radius. Since the method’s inception, it has been an open question if it possible to incorporate “multiplicities”, the parameter allowing the Guruswami–Sudan algorithm to decode up to the Johnson radius. In this paper we show how this can be done, and describe how to efficient...

[Purpose] The aim of the present study was to examine the effects of respiratory muscle warm-up on anaerobic power. [Subjects and Methods] Thirty male field hockey players (age, 20.5 ± 2.0 years) each participated in a control (CAN) trial and an experimental (EAN) trial. The EAN trial involved respiratory muscle warm-up, while the CAN trial did not. Anaerobic power was measured using the Wingat...

Power efficient communication in a Wireless Body Area Network (WBAN) is critical for successful system deployment. Stringent constraints of size and weight of sensors significantly limit available sensor power, particularly in the case of implantable sensors. This paper discusses and analyses methods that could be used to improve power efficiency of implantable WBAN systems, with focus on the W...

— This paper presents a new method of digital adaptive predistortion for linearization of Power Amplifiers (PA) exhibiting memory effects. The predistorter (PD) device consists of a Look-Up-Table (LUT) gain followed by a codebook of filters addressed by the index of the LUT. The adaptation is derived from direct learning for the LUT gains and indirect learning for the filter coefficients. We co...

Public engagement is not in tension with science, but actually a way to be more rigorous - as well as more democratic - about social choice of biotechnology.

Counter-based power models have attracted the interest of researchers because they became a quick approach to know the insights of power consumption. Moreover, they allow to overpass the limitations of measurement devices. In this paper, we compare different Top-down and Bottom-up Counter-based modeling methods. We present a qualitative and quantitative evaluation of their properties. In additi...

■ User Adjustable Slope Compensation The LT1680 is a high power, current mode switching power supply controller optimized for boost topologies. The IC drives an N-channel MOSFET switch for DC/DC converter applications up to 60V input. A high current gate drive output handles up to 10,000pF gate capacitance, enabling the construction of high power DC/DC converters. Current sense common mode rang...

Twenty-four untrained (UT) males (age 21 +/- 2.5 yr, height 1.77 +/- 0.05 m, weight 75.3 +/- 10.1 kg, values mean +/- SD) performed the Wingate Anaerobic Test (WT) under two conditions, cold (C) and following a warm-up (WU). Trials were separated by a minimum of 48 h. A modified Monark 818 cycle ergometer was interfaced with an Apple IIE microcomputer and peak power (PEAK), mean power (MEAN) an...
